It runs March 28-30, and everyone can participate. It's very easy - all you do is swim, bike, and run sometime this weekend. Anytime this weekend.
Swim a few laps in the pool at the health club or at a friend's house - check! Ride the old Huffy around the neighborhood - check! Run along the trail at the park - check! Done - you're a triathlon finisher !! Get others to do it with you - your spouse, kids, friends, grandma, whoever. I promise you'll enjoy it - there will be people all over the world doing the same.
